Answer:
2580 ft-lb
Step-by-step explanation:
Water leaks out of the bucket at a rate of
Work done required to pull the bucket to the top of the well is given by integral
Here, function
is the total weight of the bucket and water
feet above the bottom of the well. That is,
is the initial height and
is the maximum height of well. That is,
Find the work done as,


![&\left.=46x-0.05 x^{2}\right]_{0}^{60}](https://tex.z-dn.net/?f=%26%5Cleft.%3D46x-0.05%20x%5E%7B2%7D%5Cright%5D_%7B0%7D%5E%7B60%7D)


Hence, the work done required to pull the bucket to the top of the well is 
The area enclosed is (2x)(600-2x).(2x)(600−2x)=1200x−4x2
In order to maximize we need the derivative to be equal to 0.y′=1200−8x=0
1200=8x
x=150
Therefore the sides for maximum area are 150*300.

Step-by-step explanation:
1. d = rt
Divide t from both sides.

2. PV = nRT
Divide P from both sides.

3. 
Add g to both sides.
= g + a
Now multiply by 2 on both sides.
x = 2(g + a)
(or, x = 2g + 2a)
4. g
Divide g from both sides.

Now subtract 1.5 from both sides.
h = 
5.
n =
